Steam  Heating  and  Ventilation. 


HE  problem  which  is  exciting  much  attention  at  the  present  time  in 


the  science  of  warming  buildings  or  dwellings  is  to  attain  a  thor¬ 


ough  diffusion  of  heat,  at  the  same  time  keeping  the  economy  of  fuel 
and  apparatus  always  in  view. 

In  the  ordinary  heating  apparatus  of  to-day  it  is  customary  to  build  a 
fire  in  some  furnace  or  generator  prepared  for  the  purpose  and  to  circulate 
the  heat  thus  generated  by  means  of  atmospheric  air,  steam  or  water.  The 
direct  radiation  from  the  generator  or  furnace  is  not  taken  into  account  as 
a  rule,  except  in  the  case  of  hot-air  furnaces.  Hot-air  furnaces  are  ex¬ 
tremely  objectionable,  as  they  heat  a  small  area  of  metal  to  an  exceedingly 
high  temperature.  For  this  is  necessary  on  account  of  the  limited  amount  of 
heating  surface  which  is  used  by  hot  air  furnaces  to  heat  a  large  amount 
of  air.  The  results  are  that  the  air  designed  to  heat  a  building  is  intro¬ 
duced  into  the  building  greatly  de-vitalized  and  frequently  charged  with  fine 
dust  from  ashes,  to  say  nothing  of  carbonic  acid  gas  and  carbonic  oxide  which 
passes  through  this  highly  heated  metal  as  easily  as  water  through  a  sieve. 

The  objections  to  direct  systems  of  steam  heating  are,  first ,  that  there 


is  no  possibility  of  good  ventilation  where  nothing  but  direct  radiation  is 
used,  and,  secondly ,  that  all  the  direct  radiation  from  the  boiler  is  lost  and 
cannot  be  utilized  to  heat  the  house  or  building  in  question.  Indirect 
steam  heating  where  radiators  are  placed  below  the  floors  and  connected 
by  flues  and  ducts,  is  a  very  extravagant  means  of  accomplishing  the 
end,  as  cold  air  is  brought  in  direct  contact  with  steam-heated  metal, 
causing  sudden  condensation  of  steam  and  excessive  contraction  and  ex¬ 
pansion  of  the  metal  of  the  indirect  radiator  at  all  times,  thus  producing  a 
severe  strain  upon  the  radiator  and  a  costly  demand  upon  the  boiler. 

With  these  facts  well  understood,  and  knowing  the  mistakes  and  unnec¬ 
essary  expenditures  that  have  followed  from  the  use  of  these  inperfect 
systems  of  heating  now  in  use,  we  beg  leave  to  introduce  the  distinctive 
merits  and  superior  advantages  of  the  Denslow  Heating  and  Ventilating 
Apparatus. 


I'HE  DENSLOW 


Heating  and  Ventilating  Apparatus. 


The  Denslow  Heating  and  Ventilating  Apparatus  being  a  Combination 
Steam  and  Warm  Air  Heater  lias  been  perfected  by  careful  study  and  much 
thought.  The  experience  of  a  number  of  years  has  shown  it  to  possess 
all  the  better  features  of  steam  heaters  with  none  of  their  disadvantages, 
combining  same  with  an  ample  pure  air  supply  and  utilizing  the  direct 
radiation  from  the  heater  which  is  lost  in  other  systems.  Economy,  where 
it  does  not  interfere  with  efficiency,  is  largely  taken  into  consideration  in 
this  apparatus.  The  main  reason  for  this  is,  first,  that  it  utilizes  all 
radiant  heat  ordinarily  lost ;  second ,  it  diffuses  heat  perfectly,  quite  unlike 
a  furnace;  third ,  it  does  not  contaminate  air  as  in  the  case  with  furnaces; 
fourth ,  has  all  the  advantages  and  none  of  the  disadvantages  of  steam  or 
hot  air. 

To  state  the  case  briefly,  Denslow’s  Heating  and  Ventilating  Appar¬ 
atus  accomplishes  the  proper  warming  of  the  building  in  the  following 
manner : 

A  boiler  properly  constructed,  which  we  will  explain  in  detail  further  on 


a 


is  connected  with  a  warm  air  heater  in  such  a  manner  as  to  allow  for  the 
taking  out  of  steam  pipes  from  the  boiler  which  run  direct  to  direct  radiators 
on  the  upper  or  distant  rooms  and  floors  to  be  heated. 

The  rooms  nearer  the  heater  are  heated  by  warm  air  passing  through 
flues  and  registers  directly  into  the  rooms  in  the  vicinity,  and  in  each  of 
these  warm  air  flues  is  placed  an  indirect  radiator  supplied  with  steam 
from  the  boiler  which  we  have  mentioned. 

A  cold  air  flue,  from  the  outside,  enters  below  the  heater  jacket  and 
supplies  the  amount  of  fresh  air  needed  at  all  times  for  ventilating  pur¬ 
poses  and  as  a  medium  to  conduct  the  heat. 

The  direct  radiators  in  the  upper  and  distant  floors  receiving  their 
heat  from  steam  which  circulates  through  them,  causes  a  certain  action  of 
the  air  while  rarifying  it,  and  the  fresh  air  passing  through  the  jacket  of 
the  heater  is  drawn  to  upper  and  distant  parts  of  the  building  to  supply 
the  slight  tendency  towards  a  vacuum  caused  by  those  direct  radiators  we 
have  mentioned. 

As  we  remarked  before,  wherever  a  furnace  is  used  the  temperature  must 
be  high  on  account  of  the  small  amount  of  radiating  surface,  and  that  the  air 
is  badly  de-vitalized,  while  in  the  Denslow  Heating  and  Ventilating  Appar¬ 
atus  we  have  so  much  radiating  surface,  viz :  the  steam  radiators ,  both  direct 
and  indirect ,  the  combustion  chamber,  fire  pot ,  smoke  chamber ,  flue ,  steam  dome , 
boiler  and  steam  pipes ,  and  inner  side  of  warm  air  flues,  that  in  order  to 
heat  the  requisite  number  of  cubic  feet  of  air,  it  is  subjected  to  a  temperature 
at  no  time  above  250  degrees  Farenheit,  except  at  such  time  as  the  fire  is 


4 


first  kindled  in  the  heater,  for  it  has  been  proven  that  metal  heated  to  a 
temperature  above  250  degrees  is  very  detrimental  to  atmospheric  air,  if 
used  for  breathing  purposes. 

To  sum  up  our  claims  for  this  heater,  we  wish  to  say  that  we  supply  the 
necessary  amount  of  heat  together  with  an  ample  amount  of  pure  air  for 
ventilation,  and  we  can  say  boldly  that  our  system  is  more  economical  on 
account,  not  only  of  utilizing  the  direct  radiation  of  our  heater,  but  because 
the  direct  radiators  help  and  positively  enforce  the  circulation  of  the  heated 
air  to  the  most  remote  parts  of  the  building ;  and  this  result  is  not  attained 
by  any  other  system  of  heating  known. 

Another  point  which  ive  cannot  dwell  too  strongly  upon  is  the  placing 
of  indirect  radiators  in  the  warm  air-flues,  for  they  accelerate  and  ensure 
a  perfect  flow  of  warm  air  at  all  times,  and  they  are  to  be  depended  upon, 
no  matter  wha,t  the  barometrical  condition  of  the  air  may  be.  We  claim 
that  we  have  accomplished  results  with  this  combination  heater  which  it 
would  have  been  impossible  to  attain  by  any  other  heater  or  furnace 
manufactured. 

On  page  8  will  be  found  an  illustration  of  the  Denslow  Heating  and 
Ventilating  Apparatus.  The  heater  is  constructed  in  the  best  possible 
manner,  provided  with  a  rocking  grate  which  can  be  seen  in  the  illus¬ 
tration  on  page  7,  having  the  fire-pot  constructed  with  special  reference 
to  this  combination-heater,  of  ample  size  to  carry  a  considerable  bod}’  of 
coal  under  slow  combustion,  which  is  the  only  proper  way  of  running  aii)r 
heating  apparatus. 


5 


Directly  over  the  fire-pot  is  placed  the  boiler,  constructed  of  mild  steel, 
containing  lap-welded  tubes,  extending  entirely  through  the  boiler  and 
through  which  all  the  products  of  combustion  and  inflammable  gases  must 
pass,  and  utilizing  a  great  deal  of  surface  directly  over  the  top  of  the  fire- 
pot,  as  well  as  all  the  heat  which  passes  through  the  flues  to  be  absorbed 
and  taken  into  the  water  contained  in  the  boiler. 

Directly  over  the  boiler  proper,  and  connected  to  same  by  means  of  a 
4-inch  pipe,  is  a  super-heating  dome,  into  which  the  steam  passes  imme¬ 
diately  from  the  boiler  and  which  arrests  and  absorbs  into  the  steam  such 
residue  heat  from  the  fire  as  may  have  passed  through  the  boiler. 

The  smoke  flue  runs  entirely  around  this  super-heating  dome  so  that 
the  products  of  combustion  do  not  escape  from  the  boiler  into  the  smoke 
flue  until  they  have  had  a  chance  to  come  thoroughly  in  contact  with  the 
water  or  steam  which  is  designed  for  circulation  through  the  radiators,  both 
direct  and  indirect  which  are  used  in  this  system  of  heating. 

All  steam  pipes  designed  to  feed  the  radiators  mentioned  are  taken 
from  the  top  of  this  super-heating  chamber  or  dome  and  the  steam  which 
enters  the  radiators  on  account  of  its  being  super-heated,  is  very  dry  and 
at  a  high  temperature. 

The  return  pipes  from  the  radiators  are  brought  back  to  the  lower  part 
of  this  boiler  and  the  condensation  returns  by  gravity  and  no  trap  or  pump 
is  used. 

At  the  lower  part  of  this  combination  boiler  and  heater  a  fresh-air  duct 
leading  directly  from  out  of  doors  supplies  pure  air,  which  is  drawn  into  the

The  grate  is  shaken  by  means  of  a  long  lever  and  it  is  not  necessary 
for  one  to  stoop  in  order  to  thoroughly  clean  the  fire  of  ashes.  This  is 
an  advantage  which  will  be  appreciated  by  all  who  have  ever  undertaken  to 
use  the  old-fashioned  shaker.  Strongest  and  heaviest  grate  on  the  market, 
has  no  cog-wheels  or  bolts  to  get  out  of  order.  Can  be  replaced  without

BTl  1  " 

The  double-page  cut  here  shown  represents  the  Denslow  Heating 
and  Ventilating  Apparatus  with  an  indirect  steam  radiator  in  a  warm 
air  flue.  This  combination  of  Steam  and  Warm  Air  is  original  and 
found  only  in  the  Denslow  Heater,  and  insures  a  positive  circulation  of 
air  in  all  warm  air  flues  leading  to  the  floors  of  the  house  to  be  warmed. 


The  boiler  is  also  supplied  when  required  with  a  number  of  drop  tubes 
which  are  brought  into  direct  contact  with  the  burning  fuel  and  supplied 
with  diaphragms  insuring  absolute  circulation  and  greatly  increasing  the 
efficiency  and  capacity  of  the  boiler,  as  the  flues  can  be  made  to  contain 
a  large  amount  of  heating  surface,  and  this  surface  is  more  valuable  than 
any  other  in  the  apparatus. 


The  warm-air  flues  at  the  top  of  the  boiler  are  reinforced  by  an  indirect 
radiator  placed  in  an  enlargement  of  this  hot-air  flue. 

The  fire-pot,  which  is  made  of  the  best  quality  of  iron,  is  cast  over  one 
inch  thick  and  the  combustion  chamber  is  set  in  same  in  a  socket  joint  or 
groove,  and  cemented  by  asbestos  cement. 


10 


The  boiler  is  set  on  the  top  of  the  combustion  chamber  in  a  like  man¬ 
ner,  its  flanges  extending  into  the  socket  of  the  combustion  chamber  and 
likewise  cemented. 

Their  joints  are  made  in  a  like  manner  and  are  constructed  with  a 
view  to  absolutely  prevent  the  escape  into  the  fresh  air  supply  of  any  of 
the  gases  of  combustion. 

An  examination  of  our  illustration  on  pages  8  and  9  will  show 
many  of  these  points  which  we  have  described.  We  particularly  call  your 
attention  to  the  illustration  on  second  page  of  cover  containing  a  sectional 
view  of  a  house  with  a  heater,  warm  air  pipes,  indirect  radiators,  warm 
air  registers  and  ventilating  registers,  direct  radiators,  etc.,  showing 
our  system  in  operation.  The  action  of  the  heated  air  is  shown  and 
how  it  is  diffused  throughout  the  house,  as  is  also  shown  the  system  of 
circulation  and  the  arrangement  of  the  steam  supply  pipes  for  the  radi- 
tors,  as  shown  in  the  illustration  on  page  11.  It  will  be  noticed  that  the 
pipe  or  flue  is  made  much  larger  in  order  to  accommodate  this  radiator  and 
still  allow  an  ample  flow  of  air  into  the  apartments  to  be  heated.  It  will 
be  readily  understood  that  the  heat  of  this  flue  by  means  of  this  indirect 
radiator  and  its  connections  largely  accelerates  the  flow  of  air  into  the 
apartments  to  be  heated. 


Above  will  be  seen  a  very  simple  pump  for  feeding  this  boiler  with 
water,  and  this  is  an  important  feature  which  should  not  be  overlooked, 
especially  in  localities  that  are  not  supplied  with  water  works. 

11 


All  the  usual  dampers  and  cleaning  doors  are  supplied  with  this 
heater,  as  well  as  the  automatic  draft  regulator,  which,  it  can  be  readily 
understood,  regulates  not  only  the  steam  supply  but  the  hot-air  supply 
as  well,  a  feature  unknown  in  furnaces. 

The  construction  of  this  apparatus  is  such  that  it  is  impossible  for 
the  ordinary  products  of  combustion  or  gases  which  we  have  mentioned 
to  come  in  contact  with  the  fresh  air  supply,  as  the  fire-pot  and  ash¬ 
pit  are  entirely  isolated  from  the  air  supply. 

To  sum  up,  we  claim  the  following  advantages  for  the  Denslow  Ap¬ 
paratus  aud  have  endeavored  to  make  our  language  in  this  description  as 
simple  as  possible,  so  that  any  one,  even  if  he  be  not  familiar  with  any  of 
the  systems  of  steam  or  warm-air  heating,  can  comprehend  the  various 
details  of  this  apparatus.  We  are  prepared  with  many  of  the  strongest 
letters  of  recommendation,  and  on  the  next  page  will  he  found  extracts  from 
numerous  people  who  have  used  this  heater,  giving  their  ideas  as  to  its 
merits ;  and  we  believe  that  these  letters  will  corroborate  each  and  every 
claim  which  we  have  made  in  this  circular. 

Economy.  Thorough  Distribution  of  Heat. 

Ample  Fresh  Air  Supply. 

Economy  of  Cost  of  Construction. 
Utilization  of  the  Greatest  Possible  Number  of  Units  of 
Heat  from  each  Pound  of  Coal. 

Great  Efficiency. 

Great  Simplicity. 

Ease  of  Manipulation,  and  many  other  features. 

We  have  endeavored  to  give  a  careful  description  of  this  apparatus  in 
detail  with  illustrations  showing  the  different  parts  mentioned,  and  all  other 
information  interesting  and  necessary  to  those  who  desire  to  investigate  or 
purchase  the  most  perfect  heat  producer  now  on  the  market.

THE  HEATING  AND  VENTILATION  OF 


SCHOOL  HOUSES. 


It  is  a  very  surprising  fact  that,  although  schools  and  academies  as  a 
rule  are  heated  well  enough,  that,  nine  times  out  of  ten  very  little  attention 
is  paid  to  ventilation. 

In  some  schools  where  lectures  or  recitations  on  Hygiene,  Chemistry  or 
Natural  Philosophy  are  taking  place,  and  scholars  are  being  informed  that 
impure  air  when  inhaled  produces  impure  blood,  sluggish  circulation,  head¬ 
aches,  and  general  debility  ;  that  carbonic  acid  gas,  when  produced  by  exha¬ 
lations  from  lungs  or  bodies,  is  extremely  hurtful  to  the  general  health  and 
eyesight ;  that  carbonic  oxide  is  a  deadly  poison  even  in  minute  quantities  ; 
also  that  it  is  a  mechanical  possibility  to  furnish  each  and  every  individual 
in  a  school  room  with  a  sufficient  amount  of  pure  air  at  the  proper  tem¬ 
perature  for  breathing  purposes. 

While  all  these  facts  are  being  stated  the  scholars  and  teachers  are  in 
all  probability  breathing  air  so  fonl  and  impure  that  it  is  surprising  that 
they  have  vitality  enough  left  to  comprehend  what  is  taught  them. 

The  latest  dictum  from  scientific  authorities  is  that  an  adult  requires 
from  2000  to  2500  feet  of  fresh  air  per  hour  for  breathing  purposes;  that 
school  children  should  have  on  an  average  at  least  1500  cubic  feet  of  pure 
air  per  hour,  and  that  when  a  less  amount  is  furnished  bad  results  as  men¬ 
tioned  are  bound  to  ensue.  On  this  all  doctors  ai'e  agreed,  and  oculists 
state  that  one  of  the  prime  causes  of  early  failure  of  eyesight  and  astig¬ 
matism  is  impure  air  found  in  badly  ventilated  school  rooms. 


Superintendents  of  schools  and  teachers  are  frequently  aware  of  the 
terrible  condition  of  their  schools  and  try  to  remedy  it  by  opening  win¬ 
dows  or  doors.  This  never  fails  to  produce  draughts  and  there  is  an  inevitable 
inrush  of  cold  air  which  settles  to  the  floor,  and  scholars  and  teachers 
alike  must  suffer  with  cold  feet  or  breathe  foul  air. 

School  Boards  are  frequently  indifferent  on  this  subject,  but  were  they 
obliged  to  spend  a  week  at  school  subjected  to  the  discomforts  and  dangers 
of  a  poorly  heated  and  ventilated  school  room,  they  would  be  very  zealous 
in  their  efforts  to  remedy  this  crying  evil. 

The  Denslow  Heating  and  Ventilating  Apparatus  is  peculiarly  adapted 
to  the  heating  and  thorough  diffusion  of  warmed  air  in  schools  in  sufficient 
quantity  to  supply  each  scholar  and  teacher  with  from  1500  to  2500 
cubic  feet  of  warm,  fresh  air  per  hour;  this  with  all  windows  and  doors 
closed  and  no  draughts  produced. 

It  may  be  argued  that  this  result  can  be  accomplished  only  by  an 
extravagant  use  of  fuel,  but  this  is  a  mistake,  as  our  apparatus  is  so 
constructed  as  to  utilize  each  pound  of  coal  burned  to  the  best  possible 
advantage,  and  we  are  prepared  to  demonstrate  these  facts  to  those  who  are 
interested. 

We  shall  be  glad  to  furnish  estimates  for  a  perfect  system  of  heating 
and  ventilation  of  schools  and  academies,  based  011  a  thorough  knowledge 
of  the  subject,  supplying  plans,  specifications,  and  apparatus,  and  the  work 
of  construction  can  be  done  under  our  supervision  by  any  steam  heating 
contractor  that  may  be  decided  upon.

EFFICIENCY. 

Towanda,  Pa.,  April  2,  1890. 

Geo.  C.  Jackson,  Esq. 

Dear  Sir: — I  have  noticed  with  considerable  interest,  the  workings  of  the  two  large 
heaters  placed  in  our  high  school  building  by  Denslow  &  Jackson,  in  the  fall  of  1888. 

I  consider  them  successful,  for  they  do  more  and  better  work  than  four  hot-air 
furnaces  previously  in  use,  while  the  ease  in  management  and  saving  of  fuel  are  much 
in  their  favor. 

I  have  no  hesitancy  in  commending  the  “  Denslow  ”  heater  as  a  decided  advance  in 
the  work  of  steam  heating.  Yours  truly, 

JAMES  H.  CODDING,  Secretary. 

ECONOMY. 

Towanda,  Pa.,  March  28,  1890. 

Geo.  C.  Jackson,  Esq. 

Dear  Sir:- — After  using  the  Denslow  Heater  in  our  large  church  and  presbytery  for 
three  years,  I  am  more  than  satisfied  in  every  respect.  It  is  easily  attended  to,  burns 
but  little  coal ,  and  gives  all  the  heat  required  in  the  very  coldest  weather. 

Yours  truly, 

CHARLES  F.  KELLY,  D.  D., 

Rector  Churches  of  SS.  Peter  and  Paul. 


SIMPLICITY. 

I  regard  it  as  the  simplest  and  most  efficient  heater  I  have  seen.  It  has  given 
perfect  satisfaction  ever  since  it  was  put  in.  J.  H.  GREEN,  M.  D., 

February  25,  1890.  Dubuque,  Iowa. 

ENTIRE  SATISFACTION. 

It  gives  good  satisfaction  and  I  have  no  hesitation  in  saying  it  is  the  best  heater 
I  have  any  knowledge  of.  RUSH  J.  THOMSON, 

March  28,  1890.  Atty.  at  Law,  Dushore,  Pa. 


It  goes  beyond  our  expectations. 


W.  N.  REYNOLDS, 


October  16,  1890.  Propr.  Packer  House,  Tunkhannock,  Pa. 

It  is  a  great  comfort  to  us.  No  gas,  dust  or  burnt  air  from  the  heater  to  breath. 
Ventilation  is  grand.  G.  S.  SMITH, 

February  25,  1890.  Towanda,  Pa.

GOOD  VENTILATION. 


The  heat  is  pure  and  ventilation  perfect ,  is  very  economical  in  fuel.  The  longer  we 
use  it  the  better  we  like  it.  STANLEY  W.  LITTLE, 

February  21,  1890.  Atty.  at  Law,  Towanda,  Pa. 


UNIFORMITY  OF  HEAT. 

Gives  uniform  heat  throughout  the  house  during  the  coldest  weather.  No  hammer¬ 
ing  or  pounding  in  radiators  or  pipes.  Has  proven  itself  a  grand  success. 

IRVING  R.  SCHOONMAKER,  M.  D., 

March  1,  1890.  Sayre,  Pa. 


SELF-REGULATING. 

We  are  very  much  pleased  with  it,  is  self-regulating ,  takes  but  little  fuel,  no  dust  or 
gas  from  the  heater,  requires  but  a  pail  of  water  once  in  two  weeks.  Ventilation  is 
perfect.  C.  C.  MILLER, 

March  4,  1890.  Towanda,  Pa. 


MORE  THAN  FULFILLS  EXPECTATIONS. 

Does  more  than  you  claimed  for  it.  I  am  perfectly  satisfied  with  its  heating 
qualities  and  would  not  do  without  it  for  twice  the  amount  it  cost  me.  I  cheerfully 
recommend  it.  D.  W.  STARK, 

October  15,  1889.  Tunkhannock,  Pa. 

It  does  all  it  was  recommended  to  do  and  I  am  not  disappointed  in  it  in  any  respect, 
am  well  pleased  with  it.  JOHN  A.  SITTSER, 

October  15,  1889.  President  Judge  44th  Judicial  Dist.,  Tunkhannock  Pa. 


COMBINING  HEATING  AND  VENTILATION. 

The  quality  of  the  heat,  combining  indirect  heat  and  pure  warm  air,  is  a  grand 
feature  of  this  heater,  in  a  sanitary  point  of  view.  Is  like  a  pleasant  summer  heat,  at 
all  times  pure  and  delightful.  I  have  found  the  heater  very  economical  and  easily 
managed,  regulating  itself.  J.  J.  GRIFFITH, 

February  12,  1890.  President  Towanda  WaterWorks  Co. 


CLEANLY. 

There  is  no  dust  or  gas  from  it,  is  easily  managed,  requires  but  little  attention,  and 
to  say  we  are  pleased  is  putting  it  mildly.  J.  A.  DECKER, 

April  1,  1890.  of  Decker  Bros.,  Towanda,  Pa.
